 Typical use cases for the lemmatizer include:
+
 - Accessing potential German translations (glosses) of Romansh words
 - Automatically detecting the variety of a Romansh text, based on how many words are found in the respective dictionaries
 
 A limitation of the current version is that the lemmatizer does not disambiguate between multiple possible ways of lemmatizing a word. Specifically:
+
 1. If a word has multiple dictionary entries, all the dictionary entries are returned, irrespective of the context in which the word occurs.
 2. If there are multiple ways of morphologically analysing a given word form, all possible analyses are returned.
 
+## Demo Interface
+
+In the top left corner, the demo interface allows for a text to be input. Upon clicking the "Analyze" button, the lemmatizer is a applied to the text, which results in the text being split into tokens and in searching for the lemmas of each token.
+
+The idiom scores in the top right corner are calculated as the number of tokens that have a lemma in a particular idiom's dictionary divided by the number of tokens in the sentence.
+
+Underneath these two fields, the table displays the analysis of each token in the detected (i.e., the dark blue) idiom. This includes the lemma(s), if present, and a set of German translations as well as morphological annotations.
+
+At the bottom of the page, a couple of example sentences in each idiom are provided.
